No acess to dbnomics anymore
by klaus.hasenbach＠web.de
Hi,
I am quite new with gretl. In November I used gretl to retrieve data
from "dbnomics. world" sucessfuly. Great work done by the comunity!!
But now I get the message:
Fehlermeldung von dbn_get_json():
SSL peer certificate or SSH remote key was not OK
*** error in function dbnomics_providers, line 4
> err = dbn_get_json("providers", verbose, &json)
Any help? Thank you!

Great, thank you for the quick fix, Allin.
Just one question for clarification. Running the following yields an --
at least for me -- unexpected behaviour where series foo results in a
constant ("Entry_c") even though S[i] is different for each i.
<hansl>
nulldata 14000
series foo = 1 # SET to 1
strings S = array($nobs)
loop i=1..$nobs -q
S[$i] = sprintf("Entry_%d", $i)
endloop
stringify(foo,S)
print S # results in "Entry_1" for all obs
series foo = 2 # SET to 2
strings S = array($nobs)
loop i=1..$nobs -q
S[$i] = sprintf("Entry_%d", $i)
endloop
print S # results in "Entry_2" for all obs
</hansl>
Best,

bug in gap_filler() (extra v0.5)
by Artur T.
Hi all,
I think I've found a bug in the gap_filler() function which is part of
the extra package. This happens on current git using Ubuntu.
Best,
Artur
<hansl>
# extra_sample.inp
# Sample script for the extra.gfn package
include extra.gfn --force
set verbose off
open denmark.gdt -q
# WORKS: NA somewhere in the middle of the dataset
series play = LRM
play[10] = NA # insert missing
series playout = gap_filler(play, 2)
print playout
# DOESN'T WORK: Insert missing in last obs when play has a NA at the
last entry
play[$nobs] = NA # insert missing
play
series playout = gap_filler(play, 1)
print playout
# DOESN'T WORK: Insert missing in last obs when play has a NA at the
last entry
play[$nobs] = NA # insert missing
play
series playout = gap_filler(play, 2)
print playout

Gretl crash with stringify() and big dataset
by Artur T.
Hi all,
the following leads t a crash using current git on ubuntu linux (both on
18.10 and 14.04) with the message
<malloc(): memory corruption>
<hansl>
nulldata 14000
series foo = 1
strings S = array($nobs)
loop i=1..$nobs -q
S[i] = "Entry_$i"
endloop
stringify(foo,S)
</hansl>

Help with logistic regression report
by Davide Bertani
Hello everyone!
i'm a medical student from Italy, so not an expert in statistics and I
apologize in advance for my linguistic or technical errors.
I would like to ask if there is a way, using Gretl, to perform a series of
unique logistic regressions with a single command, keeping the same nominal
variable and analyzing its relationship with a series of measurement
variables extracted from an excel database. let me explain: I have a single
nominal variable , A, and a series of measurement variables B C D (100
items). usually I will open Gretl, load the database, click on "logit",
"binary", select the nominal variable and the first regressor, get the data
I need (O.R., p value, IC 95%), copy them, and paste them into Word or
Excel. then I repeat all again using the second regressor, then the third,
and so on...a huge waste of time and energies. Is there a way to avoid this
exhausting task, automating the process and performing the calculation
operation once, and then getting a table with the results in the column? Do
you think it's possible? could you help me with this task? thank you in
advance
Sincerely
Davide

AWM18
by Riccardo (Jack) Lucchetti
Folks,
the EABCN guys have just made this year's version of the AWM database
available. I packaged it for gretl and you can find it at
http://www2.econ.univpm.it/servizi/hpp/lucchetti/gretl/AWM18.gdt
I guess we could include this in the next release in place of AWM17,
couldn't we, Allin?

Estimation error in gretl
by Olasehinde Timmy
Dear Professor,
I am writing to ask for your guidance on panel regression model.
My first question is what should be the ideal dimensions of N and T in
order to use PMG and/or MG estimator?
Also, can we conduct panel unit root test for a panel of dimension T=21 and
N=4.
I hope to receiving a response from you soon.
Thanks.
Yours faithful
